General Discussion / pass only a specific block of external IP ranges to an internal port
« on: December 17, 2022, 06:45:29 pm »
I have an external spam filter that passes mail to my mail server on port 25.
I want to ensure that only mail from the spam filter is delivered to my mail server.
I setup an alias with the IP ranges for the spam filters public ip address but the server gets blocked no matter what I try.
I am setting this up on the NAT port forward.
Do anyone have an example of how to set this up?
for example I have this range setup in the alias: 72.35.12.0/255.255.255.0
Thanks,
Trent
